Air Pollution and Its Effects

Click on the flashcard to see the answer



What is air pollution?

Air pollution is the presence of harmful substances in the atmosphere that can affect health and the environment.

What are common sources of air pollution?

Common sources include vehicle emissions, industrial activity, burning fossil fuels, and deforestation.

Name a type of primary air pollutant.

Carbon monoxide is a primary air pollutant emitted directly from sources like car exhaust.

What is a secondary pollutant?

Secondary pollutants are not directly emitted but form in the atmosphere, such as ozone.

How does air pollution affect human health?

Air pollution can cause respiratory diseases, cardiovascular issues, and worsen asthma.

What is smog?

Smog is a type of air pollution characterized by a mixture of smoke and fog, often from vehicle emissions and industrial gases.

How does acid rain form?

Acid rain forms when sulfur dioxide and nitrogen oxides mix with water vapor in the atmosphere, creating acid.

What is particulate matter?

Particulate matter consists of tiny particles or droplets in the air, harmful when inhaled.

How does air pollution impact animals and plants?

Air pollution can harm animals by affecting their health and ecosystems, and damage plants by reducing growth and photosynthesis.

What role do forests play in air quality?

Forests improve air quality by absorbing carbon dioxide and releasing oxygen.

What is an air quality index (AQI)?

The AQI is a measurement that describes how clean or polluted the air is, and what associated health effects might be a concern.

Why are children more vulnerable to air pollution?

Children are more vulnerable because they have developing respiratory systems and breathe more air relative to their body weight.

What actions can reduce air pollution?

Using clean energy, reducing car trips, and promoting plant growth can help reduce air pollution.

How does the Clean Air Act help reduce air pollution?

The Clean Air Act sets standards to reduce emissions of harmful pollutants from industries and vehicles.

What is sustainable transportation?

Sustainable transportation includes options like electric vehicles, public transit, and cycling, which reduce pollution.

6. What is smog?

A type of air pollution characterized by a mixture of smoke and fog, often from vehicle emissions and industrial gases.

A natural mist that occurs during rainfall.

A clean air phenomenon that occurs at mountain peaks.

A special type of weather where visibility is very high.

7. How does acid rain form?

When sunlight splits water molecules in the air.

When sulfur dioxide and nitrogen oxides mix with water vapor in the atmosphere, creating acid.

When forests release water vapor during the day.

Through dust interaction with environmental moisture.

8. What is particulate matter?

Large solid chunks floating on water bodies.

A type of gas that clears the air.

Tiny particles or droplets in the air, harmful when inhaled.

Harmless particles of pollen in nature.

9. How does air pollution impact animals and plants?

It makes them stronger and more resilient.

It creates artificial habitats.

Air pollution can harm animals by affecting their health and ecosystems, and damage plants by reducing growth and photosynthesis.

It has no measurable effect on them.

10. What role do forests play in air quality?

Forests emit harmful gases that deteriorate air quality.

Forests have no impact on air quality.

Forests improve air quality by absorbing carbon dioxide and releasing oxygen.

Forests only affect soil quality and have no influence on air.

11. What is an air quality index (AQI)?

A measure of humidity levels in a region.

A measurement that describes how clean or polluted the air is, and what associated health effects might be a concern.

An index calculating the temperature variance across seasons.

A scale used to measure water purity levels.

12. Why are children more vulnerable to air pollution?

Because they have developing respiratory systems and breathe more air relative to their body weight.

Due to their height not reaching above pollution layers.

Because they have a natural resistance to clean environments.
